Resumen
Las coronas metal porcelana son las más utilizadas en el área rehabilitadora por su dureza, estética y valor económico. El objetivo de esta investigación es describir de una manera sencilla la apertura a través de una corona metal porcelana para lograr un correcto acceso endodóntico, a través de una revisión de artículos y libros que nos brindan bases científicas para realizar este procedimiento con los instrumentos adecuados excluyendo el riesgo iatrogénico y evitando el despegamiento de la corona metal o de la prótesis fija sin que signifique un riesgo económico para el paciente. Se trata del caso clínico de una paciente de 44 años que presenta una prótesis fija, luego de unos meses de cementación empezó la sintomatología dolorosa en las piezas pilares 11 y 23. Se realizó endodoncias en dichas piezas. Se hizo el acceso a través de la prótesis fija con la utilización de fresas: redonda y transmétalica, sin quitar la prótesis fija. Como alternativa para evitar utilizar instrumentos que ocasionan daño, tanto a los tejidos duros como a los blandos, usando instrumentos rústicos y generando las consecuencias por su uso: estrés, fracturas corono radiculares, fracturas protésicas, luxaciones, entre otros. La evolución y pronóstico de la pieza 23 realizada un año atrás, fue exitoso, razón por la cual se realizó la endodoncia en la pieza 11.Con base a este procedimiento se creó un protocolo a ser aplicado en la clínica integral de la Facultad Piloto de Odontología de la universidad de Guayaquil.
Metal porcelain crowns are the most used in the rehabilitation area for its hardness, aesthetic and economic value. The objective of this research is to describe in a simple opening through a metal crown porcelain for proper endodontic access, through a review of articles and books that we provide scientific basis for this procedure with appropriate instruments excluding iatrogenic risk and avoiding sweeping metal crown or fixed prosthesis without involving an economic risk to the patient. This is the case of a patient of 44 years has a fixed prosthesis, after a few months cementing pain symptoms began in the pillars 11 and 23. Endodontics is done in these parts. Access is made through the fixed prosthesis with the use of bits: Round and transmétalica, without removing the fixed prosthesis. As an alternative to avoid using instruments that cause damage to both hard tissues as soft, using rustic instruments and creating consequences for use: stress, root crown fractures, prosthetic fractures, dislocations, among others. The evolution and prognosis of the part 23 made a year ago, was successful, why endodontics took place in the base part 11.With this procedure a protocol to be applied in the comprehensive clinic Pilot School was established dentistry at the University of Guayaquil.
